Continuous monitoring of key risk indicators (KRIs) will provide an early warning so that proactive action can be taken, because it helps to detect and measure the changes or trends in the risk level or performance, and to alert the risk owners and stakeholders when the risk exceeds the predefined thresholds or targets. A KRI is a metric or indicator that helps to monitor and evaluate the likelihood or impact of a risk, or the effectiveness or efficiency of a control. A KRI can be quantitative or qualitative, and can be derived from internal or external sources. Continuous monitoring is a process of collecting and analyzing data on a regular or real-time basis, to provide timely and relevant information for decision making or action taking. Continuous monitoring of KRIs will provide an early warning, as it helps to identify and address the risk issues or incidents before they escalate or cause significant damage or disruption. Ensuring that risk will not exceed the defined risk appetite of the organization, providing a snapshot of the risk profile, and ensuring that risk tolerance and risk appetite are aligned are all possible outcomes of continuous monitoring of KRIs, but they are not the best answer, as they do not reflect the main purpose and benefit of continuous monitoring of KRIs, which is to provide an early warning.

The main purpose of a risk register is to enable well-informed risk management decisions by providing a comprehensive and up-to-date record of all the identified risks, their analysis, and their responses. A risk register is a tool that helps to document, monitor, and communicate the status and outcome of risk management activities. A risk register also facilitates the review and evaluation of the effectiveness of risk management processes and controls. Documenting the risk universe, promoting an understanding of risk, and identifying stakeholders are possible benefits of a risk register, but they are not the main purpose.
